As the award-winning RTE drama hits our screens this Sunday, fans will watch as the show "pushes the boundaries" to reflect what crime is really like.
"Things will get a bit darker and more exciting as we begin to push things," she said.
When asked how she felt about some commentators saying Love/Hate glamorises gangland violence, Ms McAuley denied this, saying: "Watch series three and come back to me in two months."
The show will develop a tougher edge than previous seasons as its characters get drawn further into the murky underworld.
Suzanne admitted they were far more cautious in the first season.
"There were elements that they pulled back on because it was seen as being too dark," she explained.
"We wanted to get a feel of what the audience wanted first," added Ms McAuley, who won an IFTA in 2011 for Best Drama with Love/Hate.
The new series of the show will see gang leader Nidge and his faithful lieutenant Darren get embroiled in a dangerous rivalry with a bigger gang -- the Real IRA.
Striking similarities have been made between a military style march set to be aired on the show this season and scenes from the paramilitary funeral of gang boss Alan Ryan (32), shot dead last September.
However, the producer said that while "the stories are thoroughly researched and inspired by the time we're living in", they are not based on real life crime cases.
Suzanne added that the series was written this time last year -- nine months before Alan Ryan's funeral, and any likeness between events and the series is "coincidental".
"It is a drama at the end of the day, so they're not real life stories," said Ms McAuley who also produces RTE's RAW.
Suzanne credits the creative genius of writer Stuart Carolan for providing up to date and current storylines and developing a "universal gangland feel to the show".
